From the Boston Globe, an article by Matt Surman of the Associated Press:
Another milestone for avant-garde dance legend
Cunningham turned 90 yesterday, an event paired with the premiere of a rare longer piece titled "Nearly Ninety," in which he collaborates with an architect to place the musicians up onstage with the dancers.
Trevor Carlson, the executive director of the Merce Cunningham Dance Company, said the title is a play on words.
"He hasn't talked about it, but he's made nearly 90 minutes of dance, and while he was making it, he was nearly 90 years of age," said Carlson
